Liquid magnesium chloride granulation and particle classification collection equipment and method

Abstract

The present invention relates to liquid magnesium chloride granulation and particle classification collection equipment and methods. The granulation and particle classification collection equipment includes a granulation channel, a granulator, a driver, a classification collection channel and a fluidization unit. In the liquid magnesium chloride granulation and particle classification collection equipment, the liquid magnesium chloride in the granulator flies out of the granulator due to the centrifugal force and moves toward the inner wall of the granulation channel to become magnesium chloride spherical particles and then enters the classification collection channel to control the fluidization unit The jet speed of the air injector causes the solid magnesium chloride spherical particles and the hollow magnesium chloride spherical particles to be discharged from the corresponding magnesium chloride spherical particle outlets of the first fluidization unit and the second fluidization unit respectively. Therefore, the liquid magnesium chloride granulation and particle classification collection equipment and method of the present invention can realize the classification collection of solid magnesium chloride spherical particles and hollow magnesium chloride spherical particles, thereby increasing the added value of magnesium chloride products.

Description

technical field [0001] The invention relates to liquid magnesium chloride granulation and particle classification collection equipment and method. Background technique [0002] At present, the production method of sponge titanium is mainly magnesium thermal reduction method. The method is based on Mg and TiCl 4 As a raw material, the reduction reaction is carried out at a high temperature of 800-1000 ° C to form titanium sponge, and at the same time, MgCl is also produced. 2 . MgCl 2 Its melting point is 714°C, and the temperature when discharged from the reduction furnace is 820-890°C. Currently, liquid MgCl 2 The main treatment method is that the furnace is pressurized and discharged directly into the open collection tank, and then naturally cooled in the air. This method results in a large amount of latent and sensible heat not being recovered. Although the initial temperature of bulk magnesium chloride is relatively high, it is difficult to recover waste heat due ...
